I’m not sure why people are downvoting this. Erowid is a treasure trove of first hand experiences for a huge variety of illicit substances. It’s been around forever, and you can, if I recall, generally find good, pragmatic advice on how to approach a given drug.
I've met this before. The vast majority of people on HN are pretty even-handed about things but there's just a few for whom anything that isn't anti-drug, if even just plain facts that don't show drugs in a bad light, will annoy them. Just how it is, don't worry about it.
